came contmuousiy' While I have described the construction of a ioor, it is obvious that the same is-applicable to a ceiling or a roof and in the construction of partitions. In all of these structures there will be the same bracing effect of one tile upon the adjacent tile, and the carrying of transverse stresses diagonally from the center of the span to the .point of anchorage. i, It will be noted that in specific form my improved tile comprises a flat side, an 0pposite arched sidev and transversely-extending sides .y with diagonal braces therebetween.

In the building. of ceilings it is often de'- sirablel to make provision for electrical conduits which are accessible. Such a conduit may be formed by providing tiles such as Jy Fig. 4l, innvhich the arch portion C is omitted, so that alchannel K is left. -This will not interfere with the'strength of the structure to any material extent, as the diagonal braces remain intact and coperate with those ot' theadjacent tiles.

What I claim as my invention is l. In a building 'structure7 a series of tiles of the same forni alternatively reversed and engaged with each other, each ofl said tiles being provided with a pair ot' vdiagonal braces extending between the opposite side l walls thereof, andthe abiitting faces of adjacent tiles having S-shaped interlocking portions between said braces,

Livenet l 3. In a building construction a series of.

tiles of the same form alternately reversed and engageable with each other in such p0 sition, each of said tiles being provided with Y diagonal braces between the side walls thereof adapted to aline witlrthe braces'of the adjacent tile, and one of said tiles being cut-away beyond the braces t0 form a conduit.

4. In a' buildingconstruction, a plurality of interchangeable tiles alternately in rey verse positions and having complementary external contours7 said tiles having oppositely inclined diagonal. braces betweenv the opposite sidewalls and S-'shaped portions in their abutting contours intermediate said diagonal braces forming an interlock.

In testimony whereof I aiX my signature in presence of two witnesses.
